Product Description The 1.3-inch I2C OLED Module is a crisp, high-contrast display solution perfect for adding a professional user interface to your electronics projects. Unlike traditional LCDs, OLED technology does not require a backlight; each pixel is self-illuminating. This results in deep black levels and significantly lower power consumption. While it looks similar to the common 0.96-inch display, this 1.3-inch version offers a larger viewing area, making text much easier to read. At Robogears, we frequently use this for real-time sensor dashboards, portable gaming consoles, and menu systems for CNC controllers.
Key Highlights
Self-Illuminating Pixels: Since there is no backlight, the display is paper-thin and offers an incredibly wide viewing angle (greater than 160°).
I2C Simplicity: Uses only two signal wires (SDA and SCL), saving valuable I/O pins on your microcontroller.
SH1106 Controller: Driven by the robust SH1106 IC, which is highly compatible with popular graphics libraries like U8g2.
Wide Voltage Range: Onboard level shifters allow the module to operate safely on both 3.3V and 5V logic, making it a "plug-and-play" choice for both Arduino and ESP32.
High Contrast: The 128x64 resolution provides sharp graphics and clear fonts, even in bright ambient light.

Installation Tip from Robogears It is important to note that most 1.3-inch OLEDs use the SH1106 driver, whereas the smaller 0.96-inch versions typically use the SSD1306. If you use the standard SSD1306 library, your screen might appear shifted or show "snow" on the edges. We highly recommend using the U8g2 library and selecting the U8G2_SH1106_128X64_NONAME_F_HW_I2C constructor. For wiring, connect SDA to A4 and SCL to A5 on an Arduino Uno. If you are using an ESP32, SDA is usually pin 21 and SCL is pin 22.
